The former Giants closer threw at USF on Friday as he continues to rehab from a second Tommy John surgery. Wilson still sports his trademark bushy beard, making him easy to spot, even in a city as eclectic as San Francisco.

Wilson has been hard to find since parting ways with the Giants in the offseason. When he wasn't healthy enough to make a team this spring, Wilson continued the rehab process in Hawaii.

He did not return to San Francisco for a World Series ring ceremony in April but has been seen around town this weekend. Photos on Instagram showed him playing disc golf at Golden Gate Park on Saturday.
